A new model and calculation method to solve the stiffness of muhi-leaf spring is presented in this paper. Based on the curved beam theory, a new first order differential matrix equation which used for multi-leaf spring is integrated. By using the precise integration method, a calculation method with high efficiency and precision is established. An example is offered to show the effectiveness of this method, compared to other methods.
